• Using a single Generic account multiple users are trying to login from different machines simultaneously to Mozilla Firefox. • The Mozilla Firefox is fully operational only for the first user who has initially opened Firefox session. • If the second user trying to access the Firefox with the same account, it is displayed as there is another session is already running and most of the Firefox options are getting grayed out i.e the navigation, history and forward/ backward tabs available in the menus become inaccessible.Our Requirement is that multiple users need to access multiple sessions simultaneously with all the features of Firefox available. Kindly assist me here.
